ACCURATE OPTO-ELECTRICAL MODELING OF MULTI-CRYSTALLINE SILICON WAFER-BASED SOLAR CELLS

摘要

An accurate opto-electrical modeling of multi-crystalline silicon solar cells is presented. The proposed model aimsat setting a reliable set of parameters, that will be used as starting point in future optimization studies. The trustworthiness of themodel is verified by calibrating (ⅰ) optical properties of the heavily doped emitter and of the full-area Al-based back surface field,(ⅱ) the front surface recombination velocity, and (ⅲ) the effective minority carrier diffusion length. In addition, we modeled theeffect of Al-based back surface field on the back surface recombination velocity.
